DEVICE FOR OPERATING-tHE VALVES o'F Pls-roN-METERS.

SPECIFICATION forming part of Y Letters Patent No. 252,900, dated January 31, 1882.

Application tiled June 13, 1881.

To all whom it may concern:

Be it known that l, PETER RiuvsrNK,of the city and county of Milwaukee, in the State of Wisconsin,haveiuvented certain new and useful Improvements in Water-Meters; and I do hereby declare that the following is a full, clear, and exact description of my invention,such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the letters and figures of reference marked theromwhich form a part otthis speci'- cation.

Figure l represents a perspective view of my invention. Fig. 2 is a transverse section of the same.

My improvements pertain to that class ot' meters in which a reciprocating piston is used, and relates to the device for operating the cutoft' valve through which the water passes to and escapes from the cylinder, and also in the registering device, which shows .the quantity of water used.

The objects of my improvements are, tirst, to provide a device which will operate all the valves simultaneously and instantaneously at the end of each stroke of the piston, and which will permit the said valve to remain at rest while the piston traverses the space between the respective ends ot' the cylinder, whereby' all liability of the piston bei'ng stopped midway in its stroke is obviated.

My invention'is further explained by reference to the accompanying drawings, in which A is the cylinder. B is the piston. G is the piston-rodr Distheinlet-pipe,communicating through the branch pipesE E and cut-ott' valves F and G to the respective-ends ot' the cylinder. H is the outlet-pipe, through which water escapes from the respective ends'ot the cylinder through cut-0H valves. I and J. The valves F and G are connected together by levers a a and bar l). The valves I and J are connected together by levers c c and bar d. Thebars b and d areconnected together by bars e c. Thus all the valves are turned and opened and closed by moving the bars e e forward and backward. Motion is communicated to bars e e from and by the action ot' the piston B as it reoiprocates toward the iight and (No model.)

left through standards K K, bar L, posts M M M M, and rods N N', and from said bars e e to the respective valves, as described. The

rods N Nl are adapted to move both with and loosely through their supporting-posts M M. As the piston moves from the left toward the right the rods` are carried forward with it until rod N comes in contact with the oscillating lever or catch O, by which its forward movement is arrested, until by the continuous forward movement ot` the piston Vand the accompanying attachments said catch is thrown upward and out of contact with said rod, when said rod is thrown quickly forward by the action of the spiral spring P, said spring having been previously compressed between the end standard and the pin s by the forward movement of said end standard upon said rod N against said spring. The catch or lever O is thrown up out of contact with the end ot' the rod, as described, by the inclined or angular bar R, which is secured to the side of the bar L` and is carried gradually forward with it as the piston moves. When said catch O is thrown upward and said rod N is thrown'A forward by the action of said spring, as described,the front end ot' the rod strikes the bars e c throwing them instantaneously toward the right,where by all of the cut-oft' valves'are simultaneously turned and the current ot' water reversed from the left to the right hand side of the piston. All the mechanism upon the right-hand side ot' the cylinder t'or reversing the cut-oft' valves and changing the course of the current of water from one side of the piston to the other are made and operated substantially like that described upon'the left-hand side, and the several parts and devices are referred to by the saine reference-letters.

The latch or oscillating lever is secured to the side of the cylinder A upon a standard, T, by a pivot, and it is retained in position in front ot' said rod N, when out ot' contact with the angular bar R, by the spring U, substantially as showin lt is obvious that by this arrangement the cut-oft' valves will be reversed and the course ofthe water changed from one side ofthe piston tothe other, andthe piston be caused to vibrate toward the right and left Vso long as the water flows from the outlet H.

IOO

The valves and valve-seats are constructed and connected with the water-pipes in the ordinary manner.

Motion is communicated to the registering device with eaeh alternate movement Of/the piston by the inclined bar V,whieh is attached to and moves with the bar L. As the inclined barVpasses beneath the vertical pawl W said pawl is raised thereby when it comes in oontact with the teeth of ratchet-wheel Y, thereby moving said wheel Y slightly forward. Motion is communicated from the shaft ot' wheel Y, in the ordinary manner, by a pinion to wheel A.

For registering the movements ot' the meter an ordinary seit-winding tape-measure is einployed. The free end ot' the tape is attached to the shaft of wheel A. The tape-oase C' is rigidly secured to the frame D ot' the register- 1 ing device. Thus as wheel A revolves said tape is gradually drawn from a selfwinding spool in the inelosingcase C and wound around the said shaft. The tape is provided with marks or characters by which its movement is indicated and the ow of water thereby aseertained.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a piston water-meter, the combination ot' piston B, piston-rods C C, standards K K,bar L, posts M M M M, rods N N', springs P I), angular bars R, oscillating catches O 0, springs U U, cross-bars e c, bars b and d, levers a a and c c, and eut-ott valves'F, G, I, and J, al1 substantially as and for the purpose set forth.

In testimony whereof I attix my signature in presence of' two witnesses.

PETER RENSINK.
